An infant has only cries and coos with which to communicate distress and well-being. Adults have many more ways of expressing themselves. However, their expressions of disease and ease can be boiled down to sophisticated cries and coos. A call for help in whatever form is a cry. A sense of well-being however expressed is a coo. Healing in the context of cries and coos can be viewed as the process of resolving the cries and fostering the coos.
